Celebration for the Spanish after the Revolution (5)
I believe the answer is:
revel
'celebration' is the definition.
(I know that revel is a type of conviviality)
'the spanish after the revolution' is the wordplay.
'the spanish' becomes 'el' ('the' in Spanish).
'after' says to put letters next to each other.
'the revolution' becomes 'rev' (abbreviation).
'el' put after 'rev' is 'REVEL'.
'for' acts as a link.
(Other definitions for revel that I've seen before include "Take part in lively and noisy festivities" , "Take great delight (in)" , "Make merry; luxuriate (in)" , "Spree" , "Make merry, have a ball" .)
